Air to Water

Major products: Mini air cooled chiller and heat pump, modular chiller and heat pump, air cooled screw chiller and heat pump etc.

Major type: Cooling only, heat pump, cooling only+heat recovery, heat pump+full heat recovery etc.
It needs not the dedicated machine room, also it needs not the cooling tower, but need the water pump and other water systems, the water system and control system is relatively more complicated than the air to air type, but it is more energy saving than that.
Widely used in the different type construction like restaurant, shopping mall, hospital, hotel, factory, office building and government building, school, airport, Sauna room and swimming pool etc.
